Next, we will discuss the ten most attractive programming languages on the list, including:

Rust

TypeScript

Python

Kotlin

Go

Solidity

Dart

C/C++/C#

Swift

Javascript

We will analyze the performance, requirements, and availability of each programming language.

1.Rust

Rust is a multi-paradigm programming language designed for performance and security, especially secure concurrency. Although Rust is syntactically similar to Clover checking, it can ensure memory security by using a borrowing checker to validate references.

According to the survey, Rust has become a popular language on Stack Overflow for four years in a row. In front of this huge popularity, it has been shown that people who have used Rust have fallen in love with it.

In addition, Rust allows us to store data on a stack or heap and determine at compile time when memory is no longer needed, when memory can be cleaned, and so on, so that we can use memory efficiently and have better performance.

Advantages of Rust:

The compiler provides better memory security

It is easier to achieve concurrency

Zero cost abstraction

So, whether you are a beginner or a programmer for many years, you can start with Rust. Because in the way it is used, the language is close to the established alternative.

2.TypeScript

TypeScript is now a well-known name. Since its release in 2014, TypeScript has grown rapidly and has a place in the top ten high-profile programming languages in 2021.

TypeScript was developed by Microsoft, and its emergence is actually to fill the shortcomings exposed by JavaScript.

Basically, TypeScript is used as the main programming language with Angular2 + SPA as the structure. Even the Vue .js team is using TypeScript,2018 to develop a new version of its framework using TypeScript.

The reason why TypeScript is popular is that it makes it easier for developers to write and maintain code. In addition, it provides a complete description of each component of the code, which can be used to develop large applications with strict syntax and fewer errors.

TypeScript advantages:

Class and module support

Static type checking

ES6 feature support

Clear library API definition

Built-in support for JavaScript packaging

Similar to the syntax of back-end languages (Java, Scala, .net)

In addition, TypeScript is well structured and easy to learn. Its extension toolkit can speed up our application development. Because of these advantages, TypeScript is expected to replace JS as one of the more popular programming languages in the future in 2020-2021. Many JS frameworks now provide support for TypeScript.

3.Python

Python is developing at a speed that it did not have before! Especially because of the rising trend of AI, Python has become a bigger competitor of JavaScript.

Python can be used in data science, machine learning, Web development, computer science education, computer vision and image processing, game development and many other fields.

Python is considered to be one of the easiest software languages to learn and master. For beginners, Python is undoubtedly a good entry language. Often referred to as one of the most popular programming languages in the world, Python supports the back-end stack of many startups and is crucial in the growing field of data science and AI.

Python advantages:

Very easy to use and learn

Emphasize code readability

Extensive library support

Open source programming language

Good community support

Complex applications can be extended

Build a prototype

As we can see from the picture above, Python has surpassed JavaScript in the past 5 years. In addition, it has a wide range of applications, such as Web and desktop development, web servers, machine learning, GUI-based desktop applications, enterprise and business, and data science.

4.Kotlin

Kotlin was developed by the Jet-Brains team to find "something better than Java." Many experts claim that this goal has been achieved. Like Go, Kotlin cannot be called a popular programming language. However, statistics show that the demand for the use of Kotlin is growing.

The easy interoperability between Java and Kotlin makes Android development faster and more interesting. Since Kotlin solved the major problems in Java, many developers have used Kotlin to rewrite Java applications.

According to the Hired rating (hired.com) job search website, Kotlin is one of the five most popular programming languages in the world, beating competitors such as Java and Python, second only to Go and Scala in this field.

Kotlin advantages:

Good compiler

An efficient programming language

Provide improved operational performance

Missing original type

In addition, the number of Kotlin users on Github is growing at an incredible rate. According to a report by Octoverse, Kotlin is the fourth fastest growing programming language.

5.Go

Go is the least known of all programming languages, but you can't ignore it. In 2007, Google created Go for API and Web application development.

In the past few years, Go has become one of the fastest growing programming languages. Some programmers predict that it is a good alternative to Python.

The latest report shows that Go has declined. But Go is always at the top of the list.

Go is ideal for small Web application development, API and Web servers, and so on. In addition, it includes features such as C-like language, memory management, high performance, and modern data structure support.

We can also use it for system and network programming, big data, machine learning, audio and video editing, etc.

Go advantages:

Come on!

The Book of changes

Good zooming

Comprehensive programming tools

Some trends and reports show that the popularity of Go has declined, but Go has been strong for many years and has a chance to rise again.

6.Solidity

It's time to focus on Solidity. Although the programming language is not on the Stackoverflow or Octoverse list, it is not even in the top 10 of the Pypl and TIOBE rankings. Even people in Solidity-related positions on hired.com are not in high demand.

Why is Solidity on this list? Because of the blockchain!

The demand for blockchain experts has increased by almost 517% in the past year, and the technology is new and unpopular. But blockchain and statistics show that this will change fundamentally in 2021.

Blockchain technology has become one of the most promising services in recent years, and it has great potential to change the work of the financial sector. Living in a highly digital world, many large and medium-sized enterprises are actively arranging block chain technical services in order to occupy a dominant position in the highly competitive market.

As a result, the demand for good Solidity developers will increase because it is a good choice for block chain development these days. Therefore, the demand for talent in Solidity will be very large in 2021.

The Solidity programming language is supported by the EOS platform and is a major competitor to Ethereum.

7.Dart

Dart is a client-side optimized programming language for multi-platform applications. It is developed by Google to build mobile, desktop, server, and Web applications. Dart is an object-oriented, class-based, garbage collection language with C-style syntax. At the same time, Dart can be compiled to native code or JavaScript.

Before Google announced Flutter, there was no sign of Dart. However, after the announcement of Flutter in Google Iamp O, Dart, as a local alternative, has attracted a great deal of attention from mobile developers. For developers who don't like JavaScript as a programming language, Dart has become another option. With the adoption of Flutter,Dart by Google, Alibaba and other big companies, the popularity has also been greatly improved.

Dart advantages:

Open source

Flexible

The Book of changes

Good tool support

Productivity is guaranteed.

AOT and JIT can be compiled at the same time

In addition, almost all major text editors and IDE support the Dart language. You can use a large number of IDE, such as Webstorm, IntelliJ IDEA and Android Studio, or you are free to use simple editors that you are familiar with, such as VS Code, Sublime Text, Vim, Emacs, Atom, and so on.

8.C/C++/C

These are three different programming languages, and the main focus of this article is on the scope of application of programming languages. C/C++/C# is often used in game development.

According to the report, about 50% of the world's population spends time playing games every day. The gaming industry has become very large and growing every year. The demand for game quality is also growing, and the demand for developers has always been there.

Not only the Gamin industry, embedded applications, such as robots, 3D printing, operating systems, drivers, desktop applications, such as graphics suites, desktop word processors and other industries need to use these three languages.

In addition, these three programming languages occupy a fairly high position in all scores. In Hired's ranking, C/C++/C# ranks 13th and 15th.

9.Swift

First released in 2014, Swift is a common, multi-paradigm compiled programming language developed jointly by Apple and the open source community.

Swift is a powerful and intuitive programming language for macOS, iOS, watchOS, tvOS, and more. In addition, the code written through Swift is interactive, interesting, syntactically concise, and expressive. Swift also includes modern features that many developers like. Swift code is designed to be more secure, resulting in extremely fast software.

As shown in the figure above, Swift ranks ninth in the list of 10 popular languages in 2020.

Swift has many good advantages:

Rapid development process

Easy to read and write

Requires less code

Improved performance and security

Easy to integrate with Objective-C

In addition, Swift's popularity and community support continue to grow as a result of Apple's promotion. Research data on the top 110th apps in the app store show that 42% of applications are already using Swift. If you consider only 79 of these non-gaming applications, 57% of APP is using Swift.

Although the Swift community is growing rapidly, it is far from adequate compared with other open source languages. According to the latest survey of StackOverflow developers, only 6.6% of the 87.354 respondents use Swift.

10.JavaScript

JavaScript is a famous programming language nowadays. Despite the flaw that triggers the creation of add-ons such as CoffeeScript, Flow, and TypeScript, JS is still the most sought-after in many areas.

It is known for adding interactive elements to Web applications and browsers, and most front-end developers like to use JS. In addition, the Node.js runtime provides more features than front-end development.

According to Stackoverflow, JavaScript is a popular language. According to the same survey, 66% of respondents like to use JS,17.8%. Respondents want to master JS.

As you can see, Javascript still dominates the software development world!

Javascript includes some amazing benefits:

Run instantly in a web browser

No compilation requirements

Provides a very sensitive website interface

Highly multipurpose language

Simplified implementation

You can check the Vuexy Vuejs management template and the Frest boot management template, both of which are made using Javascript.

Javascript can be used to create animations and control Web interfaces, as well as support all browsers. JavaScript can also do back-end development with the help of Node .js.
